Acast

Acast is a podcast hosting, distribution, and advertising marketplace that helps creators publish shows, distribute to every major listening platform, and monetize through dynamic ad insertion and sponsorships. Acast exposes a documented public Publishing API for programmatically managing shows and episodes - listing shows and episodes, fetching details, and creating, updating, and deleting episodes - plus placing ad markers and receiving webhook notifications for events like new episode publications. The API is documented openly at developers.acast.com, but access is gated - an X-API-Key credential is issued by Acast's customer success team to accounts on the Ace plan or in the Acast Creator Network.

Acast publishes 3 APIs on the APIs.io network: Ad Markers API, Episodes API, and Shows API. Tagged areas include Podcasting, Podcast Hosting, Publishing, Advertising, and Monetization.

Acast’s developer surface includes authentication, documentation, and 8 more developer resources.
